Summary: This patch renames the "llvm-gsym" tool directory to "llvm-gsymutil". Dependencies are also reduced to the bare minimum for llvm-gsymutil.

Lots of headers pass around MemoryBuffer objects, but very few open
them. Let those that do include FileSystem.h.
Saves ~250 includes of Chrono.h & FileSystem.h:
$ diff -u thedeps-before.txt thedeps-after.txt | grep '^[-+] ' | sort | uniq -c | sort -nr
254 - ../llvm/include/llvm/Support/FileSystem.h
253 - ../llvm/include/llvm/Support/Chrono.h
237 - ../llvm/include/llvm/Support/NativeFormatting.h
237 - ../llvm/include/llvm/Support/FormatProviders.h
192 - ../llvm/include/llvm/ADT/StringSwitch.h
190 - ../llvm/include/llvm/Support/FormatVariadicDetails.h
...
This requires duplicating the file_t typedef, which is unfortunate. I
sunk the choice of mapping mode down into the cpp file using variable
template specializations instead of class members in headers.
Now that the Windows installer no longer does anything besides
self-extract, maybe it would make sense to distribute the toolchain as a
plain zip file in addition to the current installer.

And add llvm-go back to the test dependencies.
No longer necessary now that llvm-go has been brought back.
This reverts commit e8f8873da5eaad187f82dad78ebdb3ab3df22b36.
Summary:
The type used to represent functional units in MC is
'unsigned', which is 32 bits wide. This is currently
not a problem in any upstream target as no one seems
to have hit the limit on this yet, but in our
downstream one, we need to define more than 32
functional units.
Increasing the size does not seem to cause a huge
size increase in the binary (an llc debug build went
from 1366497672 to 1366523984, a difference of 26k),
so perhaps it would be acceptable to have this patch
applied upstream as well.

isPrefix was added to support the patches to align branches.
it relies on a switch over instruction names.
This moves those opcodes to a new format so the information is
tablegen and we can just check for a specific value in some bits
in TSFlags instead.
I've left the other function in place for now so that the
existing patches in phabricator will still work. I'll work with
the owner to get them migrated.
The Blocks runtime provide a header named Block.h.
It is generally preferable to avoid name collision with system headers
(reducing reliance on -isystem order, more friendly when navigating files in
an editor, etc).

I was drafting a patch that would increase broadcast load usage,
but our shuffle scrubbing makes it impossible to see if the memory
operand offset was getting created correctly. I'm proposing to make
that an option (defaulted to 'off' for now to reduce regression
test churn).
The updated files provide examples of tests where we can now verify
that the pointer offset for a loaded memory operand is correct. We
still have stack and constant scrubbing that can obscure the operand
even if we don't scrub the entire instruction.

This was checking for default operands in the current DAG instruction,
rather than the correct result operand list. I'm not entirly sure how
this managed to work before, but was failing for me when multiple
default operands were overridden.
\<foo\> is more correct, but since we use shell=True on Windows,
the < and > get interpreted as redirection operators.
Rather than adding cmd escaping, just use \bfoo\b, which is Good
Enough Often Enough.
